Boynton Canyon
This is a popular trail northwest of Sedona, AZ. During the winter months you may find parking limited at the trail head depending upon the time of day, but there is parking allowed along the road about ~2/10 of a mile away.
From the same trail head you can also hike the Boynton Vista trail which is only 1.1 miles.
We saw some interesting web worms (picture below).
The first part of the trail overlooks the Enchantment Resort.
